At the Terminal Island federal prison in San Pedro, 600 inmates and 10 staff members have now tested positive for COVID-19. Four inmates have died.

The infection rate among inmates at Terminal Island is the highest in the nation for federal prisons. Terminal Island is a low-security facility that houses 1,053 male offenders and specializes in housing inmates who need long-term medical or mental-health care.

The prison has set up temporary field quarters with the help of the U.S. Coast Guard to separate those who are healthy from those who are infected.

Meanwhile, another Southern California prison - the California Institution for Men in Chino - is battling a coronavirus outbreak.

So far, 211 inmates at the prison have tested positive, along with one inmate death. Forty-four prison employees have also tested positive.
